Supercritical CO₂ Water‑Free Dyeing Equipment System Selected into National Catalogue A supercritical CO₂ water‑free dyeing equipment system, developed by a domestic company, was successfully included in the Ministry of Water Resources’ &ldquo...

1. Overview 1.1 What is Dye Color Fastness? Dye color fastness (also termed colour fastness or dyeing fastness) refers to the ability of a dyed textile to retain its original colour when subjected to various external factors (such as light, washi...

Here is the English translation of your provided text on color shading in reactive dyeing. Color shading (uneven dyeing) is a common quality issue encountered in the production process of dyeing and finishing enterprises. Developing a reasonable d...

Toward a Cleaner Dye Bath: Advances in Textile Wastewater Treatment and Water Reuse No stage of textile production carries a heavier environmental burden than wet processing. Dyeing and finishing generate large volumes of wastewater laced with residual dyes...

Disperse dyes are a critical category of non-ionic dyes widely used in the textile industry, specifically engineered for coloring synthetic fibers. Unlike water-soluble dyes that dissolve directly in water, these dyes feature compact molecular structures without strong hydrophilic groups—...

Driven by the "dual carbon" goals and sustainability commitments on the brand side, bio-based dyes are moving from the laboratory to industrial-scale production. Industry sources indicate that some domestic producers have adopted microbial fermentation to ma...

Reactive dyes are the workhorse for dyeing cellulosic fibers, but conventional processes require large quantities of Glauber's salt as an exhausting agent, resulting in high-salinity effluent that is difficult to treat. As discharge standards continue to tig...
